"It's game sense they [officials] need to be provided with, the rules are easy, they're black and white, but learning game sense is important in situations and I feel that's where we're missing the point.

"After coming back from Australia and the National Rugby League to here, I've found there is a real animosity from coaches toward the lack of and quality of feedback. I think that's a bridge we need to bring closer together."

Communication with the RFL

Clubs receive a visit from Rugby Football League representatives each season regarding rule changes, and are aware the referees are available to come into clubs at anytime to discuss themes and referee practice sessions if requested

Technical assistant Jon Sharp and match officials coach Ian Smith have absorbed the responsibilities of that post, including discussions with coaches and liaison with clubs, an area former Saints and Wigan coach Millward is keen to develop in the future.

"We like to have reports so we can get some good feedback about our team and areas we need to improve," the 52-year-old Australian continued.

"We also want to give some feedback from our players to referees on areas that our players have thought about.

"For example, [Castleford second-row] Lee Gilmour, who is 34 years of age and has played international football, recently said the referee [in one game] was really quiet and it was hard to hear his calls in the tackle, and from that we conceded penalties."

Cas have been penalised by the RFL on several occasions this season, notably . Team-mates Weller Hauraki and Justin Carney have also faced disciplinary measures.
